Note 1. When the A/D converter, the D/A converter and the High-Speed Analog Comparator are not in use, do not leave the AVCC0,

VREFH/VREFH0, AVSS0, and VREFL/VREFL0 pins open. Connect the AVCC0 and VREFH/VREFH0 pins to VCC, and the AVSS0

and VREFL/VREFL0 pins to VSS, respectively.

Note 2. VCL voltage must never be higher than VCC voltage.

Note 3. External VDD mode does not support in HLQFP package.

Note:

Make sure that Tj = Ta + θja × total power consumption (W), where total power consumption = (VCC - VOH) × ΣIOH + VOL × ΣIOL +

(ICCmax + ICC_DCDCmax) × VCC.

Note:

Minimum Ambient Temperature (Ta) is -40℃ or 0℃, depending on the product.

Note 1. The upper limit of operating junction temperature is 95°C, 105°C or 125°C, depending on the product.
